1 Carbon Footprint Assessments: What & Why April 28, 2011 Sponsored by: Northeast Waste Management Officials Association Pacific Northwest Pollution Prevention Resource Center Joshua Skov Good Company 1 Eugene, OR

2 overview introductions brief background: terms, science, emissions GHG inventories: context, strategy, boundaries topics for next time (May 12): how-to everyone is muted, but please type questions into the chat window; also, we ll pause at 30 minutes in (for people p to compose questions)

3 Good Company sustainability research and consulting firm mission-driven driven, for-profit clients: government, higher ed, private sector my background: economist, consultant, LEED AP, instructor in various professional development settings, adjunct faculty in two MBA programs

4 terminology climate science background on climate issues Short version: Science has told us enough that we can get working on the details. overview of US and global emissions a warning: Don t get carbon goggles! life-cycle carbon, inventory examples

5 topics that won t be covered in depth carbon markets, offsets and RECs climate risk (regulatory and physical) cost of carbon possible climate policy instruments implicit climate policy currently underway

6 background terminology global warming vs. climate change life-cycle GHG emissions, life-cycle carbon cost of carbon GHG inventory, carbon (or climate) footprint climate risk, carbon risk, cost-of-carbon risk carbon disclosure, emissions disclosure climate action, climate action planning global warming potential (GWP) greenhouse gases, GHG emissions, GHGs, global warming pollution, GWP, carbon, CO 2 e carbon is inaccurate really, all carbon dioxide equivalent (CO 2 e) emissions carbon footprint Ecological Footprint

7 IPCC summary climate science (2007) observable climate changes artic temperatures and ice, precipitation amounts, ocean salinity and warming, extreme weather and temperatures anthropogenic warming fossil fuel use, land-use change, agriculture all increase greenhouse gas concentration and global warming future changes in climate global models used in climate change simulations predict larger changes for future unless something is done IPCC AR4 Working Group 2,

8 From the IPCC in 2007: consensus on (un)certainty 8

9 cornerstone concept: life-cycle GHGs definition: the GHG emissions associated with the entire life cycle of a product, service, infrastructure component or other activity What do we know now about life-cycle GHGs for most of what we do and buy? Some of the emissions belong to us (owned). Some of them belong to others (shared). We ve never had to calculate them before. We should approach this concept with humility, as it is complex and not always intuitive. life-cycle GHG thinking is about boundaries

10 Greenhouse Gases GHGs and their GWP Global Warming Potential ti (100 yrs) Carbon dioxide CO 2 1 Methane CH 4 21 Nitrous oxide N 2 O 310 Hydrofluorocarbons HFC 140 to Sulphur hexafluoride SF Perfluorinated compounds PFC 6500 Black carbon* C? black carbon is of growing concern and its impact is not yet fully understood Source: UNEP (2011) Summary for decision makers of the integrated assessment of black carbon and tropospheric ozone

11 overview of emissions by GHG type World GHG emissions, 2004 US GHG emissions, 2009 EPA, 2011 U.S. Greenhouse Gas Inventory Report

12 energy and climate: the punch line(s) 1. The climate crisis is first and foremost an energy challenge. 2. Right now, the energy challenge is first and foremost an efficiency opportunity. 3. In the long term, the energy challenge is also a transition challenge.

19 WARNING: Don t get carbon goggles! today s focus: GHG emissions but GHG-generating activities have other impacts, e.g.: diesel/petroleum combustion: air pollution fossil-fuel extraction: oil spills atmospheric CO 2 : ocean acidification in all cases, cost solutions have unintended consequences, e.g., biofuels: habitat degradation/destruction stress on water resources food vs. fuel learn to put the goggles on and take them off, as appropriate to the circumstances

20 carbon footprints: why bother? conducting an inventory inventory protocols and calculation tools overview of the steps involved typical emission sources and issues data needs systems to collect data carbon footprints setting boundaries for your carbon footprint responsibility and mission-critical/related activities control vs. influence, owned vs. shared data availability reporting on climate performance (prelude to reporting on climate performance (prelude to climate action planning)

21 carbon footprints: why bother? you have to do it understand your climate risk (more later) impending regulation impending non-regulatory risk (e.g., supply chain) potential disruption to your business model or practices proactively manage a challenge that might matter to stakeholders live up to institutional commitments it might also be the right thing (your mission)

22 costly regulation or strategic self-knowledge? Seems like a costly regulation. Is it? Source: Bloomberg Government Insider, Winter

23 carbon footprints: setting boundaries What must the boundaries of your inventory be? regulatory requirements internal and external expectations What should your boundaries be? responsibility and/or liability: mission-critical or mission-related activities control vs. influence What can your boundaries be? data availability (proprietary data / trade secrets, state of scientific/academic knowledge) trade-offs in the inventory process itself

32 Washington (starting in 2010 for 2009) what s happening right now threshold: 10,000 MT CO 2 e total Scope I or 2,500 MT CO 2 e for a fleet Scope I trips reporting thresholds, h but must then also report Scope II Oregon (starting in 2010 for 2009) threshold: 2,500 MT CO 2 e; permit-level reporting (not entity-level), only certain types of entities) Scope I only (thresholds and reporting) California (starting in 2009 for 2008) threshold: 2,500 MT CO 2 e for electricity generation and 25,000 MT CO 2 e for certain industries Other states with mandatory reporting: NM, IA, WI, FL, NC, MD, DE, NJ, NY, VT, CT, RI, MA, NH, ME US EPA - threshold: 25,000 MT CO 2 e (not entity-level) 2 - Scope I only (for certain industries or permit holders) generally: regulatory process, not strategy

33 carbon footprints from mandatory to useful? Comprehensive reporting for informed climate strategy: all of Scopes I and II risk assessment of and scenarios for Scope II quantify and/or estimate all Scope III sources Current proactive voluntary reporting beyond Scopes I and II: dabbling in Scope III The Climate Registry s (TCR) General Reporting Protocol (GRP) Scopes I and II, except for de minimis emissions Mandatory reporting (e.g. WA, OR, CA): Scope I, maybe Scope II or worse, permit-based

34 where we will inevitably go inevitable / likely directions mandatory reporting of Scopes I and II, with thresholds tripped by the sum of I and II pervasive strategic understanding of cost-of-carbon risk via both Scopes I and II reasons for this perspective regulatory capacity / knowledge will grow quickly broader geographic and source coverage likely reality of life-cycle emissions profiles of many business models and entire sectors ease of meeting all reporting obligations with highest common denominator
